An unreleased Anthropic model made progress on one of math’s biggest unsolved problems

An unreleased Anthropic AI model has made significant progress on the Riemann hypothesis, a long-standing unsolved mathematical problem. The model coordinated multiple sub-agents to test hundreds of ideas and formalize its findings.
Why it matters
Demonstrates the growing capability of AI to contribute to complex scientific and mathematical research.
For more than 150 years, the Riemann hypothesis has stood as one of the major unsolved problems in mathematics, a long-running mystery about the distribution of prime numbers. There is currently a $1 million bounty for a working general proof of the hypothesis, which remains unclaimed.
Contemporary AI models still can’t solve it either — but they can make a lot more progress than you might expect, a finding that’s likely to reopen long-standing questions about contemporary AI’s ability to discover new scientific and mathematical ideas.
On Monday , Anthropic announced that an as-yet-unreleased model had made significant progress on the Riemann hypothesis, significantly increasing the lower bound of solutions for which the hypothesis holds true.
